Giving her take on the theme of Heavenly Bodies: Fashion And The Catholic Imagination, the 29-year-old had opted for a floaty floor-length number. The piece featured a cinched-in waist, sheer sleeves and embellishments across the bodice.

Beatrice isn’t the first royal to rock up to the Met Gala, but she is the only member of the family to have attended for the past two decades. It was back in 1996 that Princess Diana made her mark at the annual event in a navy Dior slip dress and pearl choker necklace.

However, other royals from across the world are big fans of the ball. Queen Rania of Jordan, Princess Maria-Olympia of Greece and Monaco’s Charlotte Casiraghi have all been invited in the past.
